Abstract

APARATO PARA EL TRATAMIENTO INTRACUADROS, SELECTIVO EN FRECUENCIA, DE UNA SEÑAL DE VIDEO. UNA SEÑAL DE TELEVISION DE PANTALLA ANCHA QUE CONTIENE INFORMACION DE PANEL CENTRAL E INFORMACION DE PANELES LATERALES COMPRIMIDA EN EL TIEMPO EN UNA REGION DE SOBREEXPLORACION ES TRATADA INTRACUADROS POR ENCIMA DE UNA FRECUENCIA DADA SOLAMENTE CON RESPECTO A LA INFORMACION DEL PANEL CENTRAL. EL APARATO (38) DE TRATAMIENTO INTRACUADROS INCLUYE UN CIRCUITO (1120, 1122) DE RETARDO DE SEÑAL CON UN PRIMER Y UN SEGUNDO ELEMENTOS DE RETARDO DE 262 INTERVALOS DE LINEA HORIZONTAL ENTRE UNA ENTRADA Y UNA SALIDA DEL CIRCUITO DE RETARDO. ES GENERADA UNA SEÑAL DE SALIDA TRATADA INTRACUADROS COMBINANDO (1134) LOS TERMINOS DE DIFERENCIA PROCEDENTES DE UNA VIA DE SEÑAL CON UNA SEÑAL PRESENTE EN EL PUNTO DE RETARDO INTERMEDIO. APLICACION EN TELEVISION.APPARATUS FOR FREQUENCY SELECTIVE INTRA-FRAME TREATMENT OF A VIDEO SIGNAL. A WIDESCREEN TELEVISION SIGNAL CONTAINING CENTER PANEL INFORMATION AND SIDE PANEL INFORMATION COMPRESSED IN TIME IN A REGION OF OVER-SCANNING IS TREATED IN FRAMES ABOVE A GIVEN FREQUENCY ONLY WITH REGARD TO CENTRAL PANEL INFORMATION. THE INTRA-FRAME TREATMENT APPARATUS (38) INCLUDES A SIGNAL DELAY CIRCUIT (1120, 1122) WITH A FIRST AND A SECOND DELAY ELEMENTS OF 262 HORIZONTAL LINE INTERVALS BETWEEN AN INPUT AND AN OUTPUT OF THE DELAY CIRCUIT. A TREATED OUTPUT SIGNAL IS GENERATED INTRACQUARTERS COMBINING (1134) THE DIFFERENCE TERMS FROM A SIGNAL PATH WITH A SIGNAL PRESENT AT THE INTERMEDIATE DELAY POINT. APPLICATION ON TELEVISION.
